When I first built my bike I had a box that was the same width and shape of the cargo frame and then changed to a 600mm wide one when the twins arrived, the difference i felt was insane (maybe placebo 🤷🏻♂️) but it felt like riding through treacle with a big flat square front pushing against the air.
Now my boys are riding pretty well on their own I think I’ll be making a narrower box again, will report back to see if it actually does make a difference

Frame weighs 5.8kg. I’ve calculated the ply is going to weigh 9.5kg. That’s 12mm base and 9mm sides, 12mm seat base and 9mm back. So add in the fasteners and the curvy bits and it’ll be around 16kg.
If I was still at Red Bull I could probably get that down to around 2.5kg if I made it in carbon. And I’d probably get Aero to cast their eye over it as well. Sneak it through the big claves as an R&D experiment on a common cure with some car parts and it probably wouldn’t cost any race wins etc either.
